When we engage in negative thinking about other people it upsets our own state of mind. By casting judgment on someone or being jealous of those who we perceive as lucky, we create mental anguish for ourselves. It is truly a practice to cultivate these ways of acting towards others, and absolutely helps to maintain steadiness of mind. When I let my self slip into being jealous of others or judging them, it only creates ripples of uneasiness within my own mind. To maintain calmness, steadiness and ease within ourselves we have to wish that upon others and we have to move away from negative judgment and thinking.
